After approximately 10 days of cardiac repair in mice after MI induction, NaW was administered by gavage for 28 days, and we found that CF was inhibited in the treatment group compared with the effects in the MI group (Fig. 5A, B), and the number of α-SMA+ myofibroblasts was decreased (Fig. 5C, D). This evidence concerns the gene ACTA1 and myocardial infarction.
